SIGNAL.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed. June 9, 1919, Serial No. 302,740. Renewed August 27, 1921. Serial No. 496,162.

To all whom it may concern:

Be it known that I, GERARD R. MARSICO, citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Signals, of which the following.

use is made of a heavy rotor adapted through the provision of a novel form of clutch mechanism to revolve with considerable force against the vibratory member of the signal so as to increase the number of pulsations and produce sound of greater amplitude and intensity. In my application executed May 20, 1919, use is made of a clutch mechanism for effective driving engagement with a rotor and in the structure I provided means for eliminating considerable friction between the clutch mechanism and the rotor so as to permit the latter to revolve for a long interval after driving power is supplied to the rotor.

In the form of the invention which I will thoroughly describe in proper detail I have broadly accomplished an exceedingly novel and useful functioning of parts so as to entirely eliminate friction between the clutch mechanism and the rotor whereby to permit said rotor to revolve for a still longer interval after the application of driving force thereto.

Aside from the better functioning of the instrumentalities in an elimination of friction between the clutch mechanism and the rotor, I have combined and arranged in new combinations the parts constituting the clutch mechanism so as to make the same responsive respectively to clutching and releasing movements and for exerting great radial impingement of the clutch with a coacting clutch surface ofsaid rotor.

The various important features will be particularly pointed out hereinafter in connection with a detailed description of a preferred embodiment of my invention which I have selected for illustration in the accompanying drawings, in which similar reference characters indicate corresponding parts in the several views.

In the drawings,

Figure 1 is a side view of the signal with parts broken away and parts in section. Fig. 2 is a side View of the rotor and its support.

Fig. 3 is a side view of the hanger.

Fig. 1 is a section on line 44 of Fig. 3.

Fig. 5 is a side view of the clutch devices.

Fig. 6 is'a perspective of the rotor and clutch support and the carrying axle of said support.

10 represents a suitable case having a resonator 11 and diaphragm 12, the latter having an anvil or wear piece 14. These parts I describe as one of many well-known arrangements wherein sound can be created by a vibratory member, and only to this extent do I wish to be limited when describing the principal features of my invention.

\Vithin the case is a bracket 15 carrying a fixed axle 16 on which a sleeve-like-support 17 is mounted to freely revolve. This support has extensions 18 and 19 and a pinion 20. A driving mechanism is employed for rotating the support 17 the same consisting of a gear wheel 21 suitably mounted on the bracket 15 and arranged in mesh with a rack segment 22. The segment rocks on a pin 23 carried by the bracket and extending through the bracket as an integral part of the segment is an actuating lever 24. A flexible actuating element 25 is also employed and connected with the rack segment. Said element is movable through the case 10 and is provided eXteriorly thereof with a hand gri 26. I prefer this arrangement in that due to the rough usage to which such signals are subjected there is possibility of the lever 24: being broken and the element is therefore provided as an emergency actuator. The bracket is provided with an arcuate slot 27 in which one end of a spring 28 is slidable, said end having connection at 29 with the segment. An opposite terminal 30 of the spring is suitably connected at 31 with the bracket 15 so that the segment is normally held in the position shown in Fig. 1.

' A rotor 32 is received by the extension 18 of the support 17 so as to freely revolve thereon. It carries a striking surface 33 adapted to co-act with the anvil 14 to disturb or vibrate the diaphragm. In addition thereto it carries an annular clutch surface 34 adapted to co-act with movable clutch devices 35-35 carried by a hanger 36. The extension 19 of the support 17 is fitted in an opening 36 of corresponding form in the hanger 36. This fixes the hanger to revolve with the support as will be understood. The clutch devices 35-35 are slidable in guides 37 upstruck from the hanger.

The support 17 carries cams 38 which bear against the inner ends 39 of the clutch devices. A spring 40 carried by the hanger has branches 41-41 which pass over tension pins 42- on the hanger and the free ends of said branches are extended into slots 43 in said clutch devices being normally in negagement with the walls 44 of said slots to hold the clutch devices in neutral or inactive positions as shown in Fig. 1 of the drawing,

' direction to the. support 17, causing the high sides of the cams 38 to move the clutch devices against the action of the spring' branches 41, advancing the surfaces 45 in clutch impingement/with said surface 34. The rotor then becomes fixed to the support 17 to revolve therewith during the entire period of actually expending the power applied thereto but as soon as such power is released by the returning of the segment 22 it is evident that the support 17 again assumes its normal, relatively fixed position to permit the rotor to continue to revolve by inertia. The rapidity with which the clutch devices can be thrown into and out of driving engagement with the rotor and the fact that the surfaces 45 of said devices do not in any manner contact with the rotor when the latter is spending its force are points upon which I lay particular emphasis. Quick action and reliable control of the parts is insured by the arrangements and combinations herein shown and described, while by eliminating material, resistances .between the respective clutch surfaces the rotor is caused to revolve for a very appreciable interval.

While I have herein fully shown and described and have pointed out in the appended claims certain novel features of construction, arrangement, and operation which characterize my invention, it will be understood by those skilled in the art that various omissions. substitutions, and changes in the forms, proportions, sizes, and details of the device, of the materials used, and'of their operation may be made without departing from my invention.
